Abstract: Disclosed herein is a mass spectrometer having an atmospheric pressure photoionization (APPI) source that comprises a discharge lamp coupled to a nebulizer, wherein the nebulizer is at, or near, atmospheric pressure. The discharge lamp curves around the vapor path and this coaxia...

SOLVENT DELIVERY SYSTEM FOR LIQUID CHROMATOGRAPHY THAT MAINTAINS FLUID INTEGRITY AND PRE-FORMS GRADIENTS

Abstract: A solvent delivery subsystem for a chromatography device performs relatively low pressure, high flow mixing of solvents to form a gradient and subsequent high pressure, low flow delivery of the gradient to the separation column. The mixing of the gradient is independent and does ...

DEVICE AND METHODS FOR PREPARATION OF PEPTIDES AND PROTEINS SAMPLES FROM SOLUTION

Abstract: Featured are devices, methods and kits for preparation of samples of peptides and proteins from a solution; more particularly to such devices and methods in which carbon nanotubes are utilized for sample preparation and/or purification of peptide and/or protein samples from a sol...

Abstract: The invention provides improved methods and apparatus for fluid chromatography, and is particularly appropriate to high-pressure liquid chromatography carried out using eluent flow rates less than 1 μl/minute, for example on nanoflow columns. In both single- and multi-dimensional...

Conductive conduits for chemical analyses, and methods for making such conduits

Abstract: A method for making a fluid-processing apparatus involves mixing a colloidal suspension with a matrix material, applying the mixture to a surface of a conduit, and curing the applied mixture to provide a conductive coating. A fluid-processing apparatus includes a conduit and a co...

Abstract: A method and apparatus for the continuous deposition of RP HPLC eluent, from isocratic or gradient elutions, on to a MALDI target using a parallel sample desalting method, allows increased sensitivity of the MALDI sample by pre-concentration of the analyte, separation of interfer...

Adsorption, detection and identification of components of ambient air with desorption/ionization on silicon mass spectrometry (DIOS-MS)

Abstract: The present invention provides a device, system, and associated methods to actively or passively sample air by directing it onto the surface of a porous light-absorbing semiconductor, for example, a desorption/ionization on porous silicon (“DIOS”) chip. Upon adsorption of an anal...

Apparatus and method for positioning a discharge tube with respect to an orifice

Abstract: Embodiments of the present invention facilitate servicing or changing a discharge tube or modifying the position of a discharge tube with respect to a orifice of a detector and/or a nebulizing gas conduit. The apparatus features a discharge tube housing that slidably receives a d...

Abstract: Disclosed herein is a sample preparation plate used to prepare a sample for mass spectrometry. In particular, a sample plate used to concentrate a sample as well as remove contaminants from the sample while providing easy manipulation of small liquid droplets on a surface with mi...

The always excellent Brave Combo played at the Cherry Street Brewing Company in Galesburg, Illinois on June 29, 1985. Many of us Quad-City based fans and friends of theirs attended. You can see many of us dancing up a frenzy to one of our favorite bands. Carl was nice enough to allow me to record it...
